Unified charts need synchronized valuation cutoffs, currency conversion, corporate actions, flow adjustment, and separate treatment for tokenized securities.
Stocks trade on sessions, crypto trades continuously, funds may publish daily NAV, and tokenized claims may update on another schedule. A consolidated chart must state the valuation cutoff and show which prices are fresh, carried forward, or stale. The total is only as meaningful as those conventions.
Portfolio performance should adjust for contributions and withdrawals across brokers, wallets, and cash accounts. Internal transfers and asset transformations belong in a reconciliation layer. Exposure can then be grouped by asset class, issuer, sector, chain, protocol, currency, and liquidity without forcing one taxonomy to answer every question.
Each layer answers a different question. The summary remains useful because the supporting evidence is still available.
Use a documented cutoff and show market status, price age, currency conversion, and missing observations.
Separate contributions, withdrawals, internal transfers, dividends, rewards, fees, and market movement.
Record splits, dividends, mergers, migrations, rebases, wraps, and airdrops as explicit transformations.
Group by asset class, issuer, sector, chain, protocol, currency, liquidity, or account.
Definitions are descriptive, not promises of completeness. Protocol and network implementations can differ.
The timestamp and price rule used to value all included positions for a snapshot.
The last eligible observation used when a market is closed or a new value is unavailable.
An issuer event such as a split, dividend, merger, or spin-off affecting quantity or value history.
External capital added to the tracked portfolio, distinct from investment return.
A grouping based on underlying economic assets while preserving the held instrument.
The difference between current weights and a user-defined reference mix.
Yes, if valuation times, prices, currencies, flows, and stale observations are documented. Separate series should remain available.
A chart can carry forward the latest stock price while marking it as stale, or use another stated convention. It should not imply the stock moved while its market was closed.
Not automatically. The token may represent a different claim with its own issuer, custody, transfer, pricing, and redemption terms.
